Poly(ionic liquid)s for Photo‐Driven CO2 Cycloaddition: Electron Donor–Acceptor Segments Matter
Advanced Science, 2023 CO2 cycloaddition with epoxides is a key catalytic procedure for CO2 utilization. Several metal‐based catalysts with cocatalysts are developed for photo‐driven CO2 cycloaddition, while facing difficulties in product purification and continuous reaction ...

Palladium-Catalyzed [3+2] Cycloaddition via Two-Fold 1,3-C(sp3)−H Activation [PDF]
, 2020 Cycloaddition reactions provide an expeditious route to construct ring systems in a highly convergent and stereoselective manner. For a typical cycloaddition reaction to occur, however, the installation of multiple reactive functional groups (π-bonds ...

Diastereo- and Enantioselective (3+2) Cycloaddition of a New Palladium-Aza-Oxyallyl Intermediate [PDF]
, 2023 Cycloaddition of azaoxyallyl cations or other C-(C=O)-N synthon precursors is a well-established route towards lactams and other N-heterocycles but, despite the wide synthetic scope of this approach, enantioselective versions remain scarce.

A Stepwise [4 + 3] Cycloaddition Reaction of the 1,3-Diphenyl-2-azaallyl Anion [PDF]
, 1993 The 1,3-diphenyl-2-azaallyl anion (1) undergoes [3 + 2] cycloaddition reactions with the s-cis-fixed 1,3-dienes 8-11. In contrast, 1,1,2,2,3,3-hexamethyl-4,5-bis(methylene)cyclopentane (7) reacts with 1 to give the [4 + 3] cycloadduct 13 and the linear 1,
